The difference between AC ion fan and DC ion fan
The difference between an AC ion fan and a DC ion fan. The difference between an AC ion fan and a DC ion fan is that a discharge needle of the AC ion fan can alternately generate positive and negative air ions, and the discharge electrode is composed of a discharge needle and a ground electrode. , The discharge electrode of the DC ion blower does not need a grounding electrode, and the discharge electrode is composed of separate discharge needles for positive and negative.
When there is no external air supply (such as fans, compressed gas, etc.), the DC ion fan has a longer distance to remove electricity than the AC ion fan. In the case of external air supply, the neutralization distance mainly depends on the structure and The air volume and the strength of the high-voltage power supply. The difference between AC>ion fan and DC ion fan is the difference in ion balance. The AC ion fan generates both positive and negative ions on the same discharge needle, so even if the discharge needle is worn for a long time, the ion The balance will not change much, and the ion balance performance is better.
Since the discharge needle is composed of independent positive and negative electrodes, the ion balance is poor when used at close range. In addition, the discharge needle is affected by the environment and the degree of contamination of the needle during use will affect the ion balance, especially the discharge needle After long-term use, the degree of wear of the positive and negative discharge needles is different, and the ion balance cannot be corrected even after cleaning.
